Lines are the simplest type of function. It’s important to be able to graph them and calculate the slope (i.e., the rate of change), which is one of the most fundamental concepts in Calculus. While lines have a constant slope, the slope of other functions continuously changes. Understanding lines is the first step toward working with curves.
